Jim Simons' s Profile & Performance

Profile

In 1982, Simons founded Renaissance Technologies Corporation, a private investment firm based in New York with over $20 billion under management; Simons is still at the helm, as CEO, of what is now one of the world's most successful hedge funds.

Investing Philosophy

For over two decades, Simons' Renaissance Technologies' hedge funds, which trade in markets around the world, have employed complex mathematical models to analyze and execute trades, many of them automated. Renaissance uses computer-based models to predict price changes in easily-traded financial instruments. These models are based on analyzing as much data as can be gathered, then looking for non-random movements to make predictions.

"The advantage scientists bring into the game is less their mathematical or computational skills than their ability to think scientifically. They are less likely to accept an apparent winning strategy that might be a mere statistical fluke."

5 Deep Value or Net-Net Investment Ideas 5 companies that score well on GuruFocus' Graham Net-Net screener Jim Simons,First Eagle Investment,Chuck Royce,Paul - 5 Deep Value Or Net-Net Investment Ideas
Ben Graham popularized net-net investing, and this is one area of the market where I like to look for undervalued companies. Net-net investing means investing in companies that trade at a price that values them below the value of current assets. It is a very strict valuation rule because it means the company trades below the value of its cash and cash equivalents, accounts receivable (adjusted for doubtful accounts) and inventory (which you should adjust as well). The total of all liabilities is then deducted from current assets to arrive at a net-net value. Obviously it is a lot of work to go through this excercise with every company in the U.S. It is much easier to use GuruFocus' net-net screener, but make sure you read the criteria on which it relies.
